Specification of Letters Patent.

Patented Nov. 27, 1917.

Application filed June 7, 1915. Serial No. 32,572.

T 0 all wkom it may concern:

Be is known that I, LOUIS ToUrIN, of West Warwick, in the county of Kentand State of Rhode Island, have invented certain new and usefulImprovements in Guide-Holders for Pile-Cutting Machines; and I do herebydeclare the following specification, taken in connection with theaccompanying drawings, forming a part of the same, to be a full, clear,and exact description thereof.

The invention relates to a guide-holder for holding the knife-guide in amachine for cutting pile fabrics. Heretofore it has been customary tosolder the knife-guide to the guide-holder, thereby making the twostationary with relation to each other. With such a construction andarrangement great skill and care must be exercised in soldering theknife-guide to the guide-holder as the slightest turning of theknife-guide from its proper position will result in crapy cutting of thepile and produce an imperfect fabric. Furthermore when the guide-holderis soldered to the. knife-guide it interferes with the free manipulationof the knife-guide while grinding or sharpening the same.

It is the object of the present invention to obviate these objectionablefeatures and to produce a guide-holder in which the knifeguide isremovably mounted, so that when a knife-guide is broken, a new one canbe easily and quickly mounted in the guideholder in proper position andwithout the exercise of any skill.

To this end the invention consists in the novel form of guide-holderhereinafter described and more particularly set forth in the claims. Indescribing the invention in detail reference will be made to theaccompanying drawings, in which- Figure 1 is an end view of my novelguide-holder.

Fig. 2 is a side view of the same.

Fig. 3 is a top plan view of the guideholder with a knife-guide mountedtherein.

Fig. 4 is a side view of the same.

Fig. 5 is a side view of the knife-guide.

Fig. 6 is a top plan view of the same.

Fig. 7 is an end view of the same.

Referring to the drawings, the guideholder comprises a wedge-shaped bodyportion 1 having a flat circular end portion 2. Secured to the endportion 2 is a lateral stud 3 provided with a cam-projection l of theusual construction. The body portion 1 is provided upon the sideopposite to the stud 3 with a downwardly extending lip 5 arrangedsubstantially parallel with said body portion to form a slot or groove 5and upon the same side with an upwardly ex tending lip 6 arrangedsubstantially parallel with said body portion to form a slot or groove6, as shown in Fig. 1.

The knife-guide 7 is wedge-shaped and is provided with a longitudinalslot or channel 8 to receive the knife. Said longi tudinal slot 8 makesthe large end of the knife-guide 7 U-shaped in cross-section, as shownin Fig. 7. The knife-guide 7 is mounted in the guide-holder by insertingthe pointed end in the slot 6 and forcing said knife-guide forward untilit is wedged in position. As the knife-guide is forced forward thedownwardly extending lip 5 enters the slot 5 and as said slot 5 isnarrower than the leg of the U-shaped end portion which engages thesame, and as the slot 6 is narrower than the large end of theknife-guide, a spring action will be set up in each of said lips 5 and 6and said knifeguide will be wedged in position in the slots 5 and 6 ofthe guide-holder. When the knife is inserted in the longitudinal slot 8of the knife-guide it will tend to separate the legs of the U-shaped'endportion and force them against the sides of the slot 6, therebyincreasing the wedge action.

With the above construction of guide holder it will be seen that theknife-guide can be easily and quickly mounted therein or removedtherefrom without the use of solder and without detaching the guideholder from the machine.

What I claim as my invention and desire to secure by Letters Patent is:

1. An article of the character described comprising a body-portionprovided with a slot upon one side arranged and adapted to receive aremovable U-shaped knife-guide.

2. An article of the character described comprising a wedge-shapedbody-portion provided upon one side with a downwardly extending lip andan upwardly extending lip, each of said lips being arranged to form aslot between the lip and the bodyportion.

3. An article of the character described, comprising a body portionprovided upon lllld one side With a narrow slot at the top and wardlyextending lip and the'body portion a Wide $1013 at the bottom. and thedownwardly extending lip project- 10 7 4.
